It is normal for a laptop battery life decrease as more and more cycles you run on your laptop battery. The estimate life for a laptop battery is around 1 year to 1 and a half year depends on how your use you laptop and how many cycles you run on your laptop battery.

Power Rating Terms Every laptop battery is given a power rating in order to show you, the consumer, about how long your battery should last before it needs to be recharged. These electrical specifications are given using volts (V) and milliAmps (mAh). For example, you may s...

Most laptops now use lithium ion (LiIon) batteries. LiIons should be managed differently from the NiCad or NiMH batteries used in older laptops. In particular, LiIons should not be run all the way down to prevent "memory effect". First, they don't have a memory effect, and second, running them down tends to reduce their capacity. If the laptop does not need the battery it should be run to about 40% charge and stored in a cool place. See similar questions...

Run time can be increased or decreased depending on the applications and tasks that you have your laptop doing. For example, if you are playing a DVD movie, much power is being used. If you are burning a CD-R/CD-RW or playing a full screen 3D video game, much power is being used.... See similar questions...

One cycle of a battery is a discharge from full charge to full discharge and a return to full charge again. The total number of cycles a battery can perform before failure is called its Cycle Life. Most battery manufacturers will not discus the Cycle Life of their product. Many advertised Deep Cycle batteries have not been tested, or, which is the case with cranking batteries, were never designed for long Cycle Life. See similar questions...

Yes, it is very important to condition or fully discharge and then fully charge the battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run the device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user's manual.(Return to Top) See similar questions...

A battery's running time is very difficult to determine as it depends on many varying factors; such as the use of the screen, hard drive and all other accessories. These factors effectively reduce the battery's running time, so the more power demands made on the battery by the equipment, the shorter the running time. The total running time of the battery is also dependent upon the design of the equipment. A new Hi-Capacity battery will run 30% to 50% longer than the old battery did when new.

It's a fact. Let's consider how a typical MP3 player works. In a MP3 player, at least 70 percent of the battery power goes to running circuitry that produces the audio output for you to listen. As the battery power is drained. The audio signal is the first thing that diminishes. When this happens, you have to crank up the volume to make up for that loss, and then audio quality becomes more distorted. However, turning up the volume on your player also drains the batteries faster. See similar questions...

This article is from the NYT: April 6, 2006 Helping Batteries to Keep On Going and Going By PETER WAYNER What good is a tiny thin sliver of electronic gadgetry if the battery dies in your pocket after a few minutes? Not much, and now that manufacturers have mastered the building of pocket-sized wonders that are often too small for our fingers, they are starting to pay closer attention to battery life. New machines come with smarter batteries and miserly circuitry that works longer. See similar questions...

There are three battery technologies in common use these days. Each of these battery technologies has its own unique properties and its own peculiar charging requirements. Here is a summary of those available technologies: This is the oldest of the three technologies, but you will still find quite a few batteries of this type still around. Cadmium is extremely toxic, and so this type of battery has been slated for extinction in the near future. See similar questions...
